The title describes it well.
Theoretically snarl displays tons of notifications at the same time.
Could be useful to have limit to set. (in total or per extension is up to you, or could be user selected)
Let's say 10. Then Snarl would display only 10 at once. But what's about the others?
Show exceeding later (delayed)
Drop them (do not show them)
Thank you for attention.
